IVF Success Rates

IVF Success Rates Explained

We are proud to be SART members and, as such, are required to report our statistics to the CDC National Registry. We do so, and are quite proud of our statistics, but feel that patients and potential patients need to understand the complexities involved. Program statistics should only be a small part of the decision-making process involved in selecting a program.

Implantation Rates are one of the most important things to look at when comparing IVF clinics as it factors in both the number of embryos the clinic transferred and the rate that the embryo(s) implanted in the uterine wall, which is a necessary step in pregnancy. Our PGS implantation rate per embryo for 2017 is: 82%

Our 2018 stats are reflective of 379 cycle starts.

These amazing rates are the result of both our highly trained staff and our never ceasing push to incorporate new technologies and techniques such as freeze-all cycles and genetic testing (PGS/PGD) to give our patients their best chance at success.

Please note that a comparison of clinic success rates may not be meaningful because patient medical characteristics, treatment approaches, and entry criteria for ART may vary from clinic to clinic.

How does ORH compare with other clinics?

The very best number that you can use to know how a clinic is doing is to look at implantation rates per embryo. This rate is so useful as it illustrates what percentage of the embryos the clinic transferred resulted in pregnancy.

What you are left with is a good reflection of how good a particular clinic is. From the beginning of 2016 through September 2017 our implantation rate per embryo, for all age and treatment groups, is 81%!(click for the details)

Putting it all into perspective

There are three kinds of lies: lies, damned lies and statistics. -Autobiography of Mark Twain

All statistical methods assess data from populations.

But a patient is not a population.

Each patient has a unique set of circumstances that defines their own specific likelihood of achieving a pregnancy.

IVF statistics will look good if population data is controlled.

In the words of a famous European infertility expert:

The patients who are easiest to get pregnant get pregnant most easily.

Let’s look at two different types of Physicians Practice Statistics, Dr. Lookgood and Dr. Helpall:

Dr. Lookgood

Pregnancies, ongoing/births

Dr. Helpall treats patients according to a philosophy typical of medicine in most fields, and the philosophy that we believe is the correct one:

Take patients in the order that they come to you, help those who have a chance of being helped, do your best for each individual patient, and let population statistics fall where they may.

As you can see, Dr. Lookgood has a different vision. Take a second look at the same data as reported following the guidelines of the National Registry.

At Overlake Reproductive Health we are quite proud of our IVF success rates. We strive to treat those patients whom we can help. We don’t try to pre-select our patient population in order to benefit our statistics. Our IVF success rates are “real.”

While we are understandably proud of our IVF success rates, with upward trends attributable to an unremitting introduction of cutting edge ideas and technology, it should be noted that a comparison of clinic success rates may not be meaningful because patient medical characteristics and treatment approaches may vary from clinic to clinic.

Patient Review

ORH has been a godsend. They did all my testing, discovered I have a fertility affecting condition and prescribed me medication that has been effective. I am amazed at how quickly they found the problem and a solution. I am very grateful to them - all the staff are wonderful and compassionate. I am now 8 weeks pregnant - less than four months after I started going to ORH. Thank you ORH!
